We recognize two new species of Asteraceae from the winter rainfall belt of South Africa and reduce a third to synonomy.  Senecio speciosissimus sp. nov. has been confused with  S. coleophyllus Turcz. in the past but is distinguished by its taller stature, larger and more finely serrated leaves, and congested synflorescences containing (6-)l 5-40 flowerheads. The two species are also geographically separated:  S. speciosissimus occurs in the Hottentots Holland and Franschhoek Mountains of the southwestern Cape, whereas S.  coleophyllus is endemic to the Riviersonderend Mountains.  Chrysocoma hantamensis sp. nov. is a distinctive new species endemic to the Bokkeveld and Roggeveld Plateaus. It is distinguished by its resprouting habit. 3-5-fid leaves and large capitula, 12-15 mm in diameter, with lanceolate. 3-veined involucral bracts, the largest 9 - 1 0 x 2 mm. Investigation of the variation in leaf morphology of the two radiate species of Oncosiphon, O. africanum (PJ.Bergius) Kallersjo and  O. glabratum (Thunb.) Kallersjo. reveals that only one species can be maintained, and O. glabratum is accordingly reduced to synonomy in O. africanum.

Gladiolus rhodanthus is a new species known from a single population on the summit of the Stettynsberg near Villiersdorp in Western Cape. South Africa The species most closely resembles G. hirsutus and G caryophyllaceus but differs from both in flower shape and markings and in its ecology and reproductive biology. It forms part of a guild of long- tubed, pink-flowered species including  Erica praecox, Pelargonium radiatum and  Watsonia paucifolia which are pollinated by an undescribed long-proboscid fly. Moegistorhynchus sp nov. (Diptera : Nemestrinidae). Gladiolus sekukuniensis is a new species known from three populations south of the Strydpoortberge in Northern Province It closely resembles G. permeahilis subsp  edulis in vegetative features and in flower form, but differs from it in flower colour and in the elongate peri­anth tube. These floral features are apparently adaptations to pollination by long-proboscid flies.

Newly described are two new species of Spiloxene Salisb.:  S. nana Snijman from the Bokkeveld Escarpment, Northern Cape Province, is a shade-loving plant with narrow, pale green leaves and small, white or rarely cream-coloured flowers; S. pusilla Snijman from the Matsikamma, Gifberg and Pakhuis Mountains. Western Cape Province, resembles S. nana in habit but the yellow- or white-tepalled flowers which are tetramerous or hexamerous have darkly coloured stamens and style and an ovary with a short, solid, narrow prolongation at the apex. Inhabiting rock overhangs formed by quartzitic sandstone sheets, both species are close allies of S. scullyi (Baker) Garside from Namaqualand.

A new phytoptid genus and two new species, Solenocristus karooensis n. g. & n. sp. and S. searsius n. sp. (Phytoptidae, Sierraphytoptinae, Sierraphytoptini), were collected in the Eastern and Western Cape provinces of South Africa, from southern African endemic dicotyledonous trees Schotia afra (Fabaceae) and Searsia lucida (Anacardiaceae) respectively. They are described and illustrated with the aid of conventional light microscopy and low temperature scanning electron microscopy. Females of both new species possess a distinct pregenital plate divided into two parts by a subcuticular medial ridge. Additionally, in S. karooensis n. sp. the movable digit of the male chelicerae varies in length: among six observed males, three males had a movable digit (md) twice shorter than the fixed digit (fd), in one male it was slightly shorter than fd and in the remaining two males md and fd were of the same length. An updated key to the world genera of the tribe Sierraphytoptini is given. The key incorporates data on seven sierraphytoptine genera including three genera (Neoprothrix Reis & Navia, Solenoplatilobus Chetverikov & Craemer and Solenocristus n. g.) which were described since the last generic key of Eriophyoidea by Amrine et al. (2003) was published.

Plants until now identified as Drimia marginata (Thunb.) Jessop on account of their leathery, oblong to elliptical leaves with thickened, cartilaginous margins and capitate inflorescences of campanulate flowers, are shown to comprise three sets of populations separable on leaf morphology, ecology and distribution. Typical D. marginata produces 1 (2) oblong, apiculate leaves with retrorsely-scabridulous margins and occurs in fine-grained clay soils on the Hantam and Roggeveld Plateaus. Plants from Namaqualand and the Richtersveld. described here as Drimia pulchromarginata J.C.Manning Goldblatt. occur in sandy or gravelly soils and produce 2 -4 , elliptical to suborbicular, apiculate leaves with an ornate, duplex margin: the dorsal surface bears a submarginal band of dense, velvety trichomes fringing the thickened, colliculate margin. A third series of populations from seasonally moist sandstones at higher altitude on the interior mountains of the West Coast produces2 or 3(4) narrowly oblong, obtuse leaves with a simple, papillate or colliculate margin and are recognized as D. ligulata J.C.Manning Goldblatt. A fourth taxon with a similar capitate inflorescence of campanulate flowers produces a solitary, subterete or subclavate leaf, elliptical in section. Recorded from scattered localities in the Northern and Western Cape', it is here described as D. vermiformis J.C.Manning Goldblatt.

Pelargonium hammansbergense and P. roseopetalum are described as new species. Both are deciduous geophytes with turnip-shaped tubers belonging to P. section Hoarea. These two species share spathulate petals with narrow cuneate claws.  However, they differ in leaf shape, flower colour and markings on the petals. Their flower structure corresponds to that of P. aridicola, P. hirtipetalum, P. pubipetalum, P. reflexipetalum and P. tripalmatum. The seven species are compared with regard to the flower and leaf morphology, palynology and chromosome numbers. They all occur in the winter rainfall region along the west coast of South Africa. The two new species described here are illustrated and a key for the identification of the seven species with a P. aridicola flower type is included.

The present study is based on oribatid mite material (Acari, Oribatida) collected from soil of Kaaimansgat estuary, Wilderness, Western Cape, South Africa in 2018. A list of identified taxa, including 41 species from 34 genera and 23 families, is presented; of these, nine species, three genera and one family are recorded in South Africa for the first time. Two new species belonging to the family Oppiidae are described: Kokoppia kaaimansensis sp. nov. differs from Kokoppia dudichi (Balogh, 1982) by the larger body size, the medium sized lamellar and interlamellar setae, the presence of muscle sigillae in the interlamellar region and the distinctly semi-oval epimeral borders IV and the absence of notogastral setae c; Paroppia neethlingi sp. nov. differs from other species of the genus by the localization of adanal lyrifissures in a direct apoanal position and the absence of epimeral borders IV. Revised generic diagnoses and identification keys to the known species of Kokoppia and Paroppia are presented.

The Australian members of the vetigastropod family Anatomidae are revised and two new species are described. The family has thus far been treated as a subfamily of Scissurellidae, but recent molecular evidence (Geiger & Thacker, unpubl. data) indicates that Scissurellinae plus Anatominaeis not monophyletic, and full family rank is warranted for a group containing the genera Anatoma and Thieleella. Seven species from Australia belonging in Anatomidae are discussed and illustrated by SEM: Anatoma aupouria (Powell, 1937) mainly from New Zealand, though with some Australian records; A. australis (Hedley, 1903), A. funiculata n. sp., An turbinata (A. Adams, 1862), which has been misidentified in the past as the South African A. agulhasensis (Thiele, 1925), A. tobeyoides n. sp., Thieleella equatoria (Hedley, 1899) with a second known specimen, and T. gunteri (Cotton & Godfrey, 1933). Other species that have been (erroneously) indicated from Australia are discussed. A neotype is designated for A. agulhasensis from South Africa for taxon stabilization.
